SMOKE CONSUMER Filed Nov. 1e. 41929 s sheets-sheet 3 INVENTOR Patented May 16, 1933 UNITED STATES PATENT OFFICE CHARLES H. MIKODY, F CHICAGO, ILLINOIS SMOKE CONSUMER This invention relates to a smoke consumer for use with any kind of a heating system or other system or apparatus which produces smoke, the general object of the invention being to provide means whereby all the obnoxious elements in the products of combustion from a smoke producing device are eliminated so .that the residue can be expelled into a room or any other place without causing 0 discomfort or injury to persons, etc. in said room or place. Thus this invention will eliminate the use of chimneys and other exhaust means for smoke producing apparatus.

Another object of the invention is to provide means whereby all the heat is extracted from the products of combustion so thatI the room or other place to be heated is heated with the minimum amount of fuel.

A still further object of the invention is to arrange the invention on a wheeled support so that it can be pushed from one room to another to heat the various rooms,

This invention also consists in certain other features of construction and in the combination and arrangement of th'e several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawings wherein. like characters denote like or corresponding parts throughout the several views, and in which Fi re 1 is a sectional view through a truck or ot er wheeled support, showing the invention thereon, the parts of the invention being shown in elevation. y

Figure 2 is a sectional view with parts in elevation of the tank and the parts associated therewith. n

Figure 3 isa sectional viewthrough the small tank arranged above the large tank.

Figure 4 is a sectional view through the pump.

Figure 5 is an elevation partly in section through the purifying-means used when the pump is not in operation.

Figure 6 is a sectional view through the `heat extracting means which receive the -`products of combustion from the stove.

Referring to Figures 1 to 6, both inclusive, the numeral 1 indicates a stove or other heating element and the numeral 2 indicates a pipe through .which the products of combustion from the stove pass. This pipe leads 55 the products of combustion into a drum 8 from which they pass through the four pipes 4 into a second drum 5 which is supported from the first drum by the tubular connection 6. A pipe 7 leads the products of com- 60 bustion from the drum 5 into a drum 8 which is provided with an outlet pipe 9, this outlet pipe being connected by the small pipes 10 with the intakeof a gear pump 11. A small drum 12 is connected with the top of the drum 65 8 by the pipe 13 and pipes 14 connect the top of the drum 172 with a depending part of the pipe 9. Pipes 15 lead the products of comustion from the outlet of the pump to a pipe 16 which extends downwardly through the top of a tank 17 which contains a liquid 17 having a suitable chemical therein. The pipe 1 6 extends an appreciable distance into the liquld so that the products of combustion escaping from the pipe must pass upwardly through the liquid and thus be cleaned thereby. A filter 18 is placed in the upper part of the tank and acts to filter the products of combustion passing from the same.

A pipe 19 connects the top of the tank 17 80 With a small tank 20, while within said latter tank and attached to the upper end of the pipe 19 is a pressure valve 21. A filter 22 is also arranged in the tank 20 above liquid 23 in said tank, this liquid also containing chemicals and is similar to the liquid in the tank 17 The pressure valve 21 will prevent the products of combustion from passing into the tank 20 until a certain pressure eX- ists in the tank 17. Pipe 24 conducts the residue of the products of combustion from the tank 20 tothe lower draft opening of the stove, a valve 25 being arrangedv in said pipe line and a branch line 26 leads some of the residue from the tank 20`to a nozzle 27 95:

in the pipe 2, this line also containing a valve 28. The remaining residue of the products of combustion is ca Tried by a pipe 29 into a discharge member 30 which is formed of wire mesh 30 covered with cloth 30, as shown in 109 Figure 5. From this member, the purified residue of the products of combustion escape into the atmosphere.

Thus it will be seen that the products of combustion passing through the drums 3 and '5, the pipes 4 and 7 and the drums 8 and 12 and their pipes will have all heat contained therein extracted by said drums and pipes so that the room or other place in which the apparatus is located will be heated with the minimum amount of fuel. The pump acts to give a circulation to the products of combustion and as it is a geared pump, its gears t 2 to increase the draft of the stove and the Iwill not cause discomfort or injury lto persons in the room, and the use of a chimney or other discharge for the smoke is eliminated. rlhe ilow of the purified residue to the nozzle and stove is controlled by the valves 25 and 28.

The pipe 2 contains the usual d amper 31 and a screen 32 is placed in the pipe below the drum 3 to prevent particles of foreign matter entering the drums. The nozzle 27 discharges into the pipe 2 between the damper and the screen. It will, of course, be understood that some of the products of combustion passing in the drum A8 will pass directly through the pipe 9, while another ortion will pass through thek drum 12 and its pipe 14 into the pipe 9. A discharge pipe 33 is connected with the bottom of the drum 8 and contains a valve 34, so that any foreign matter collecting in the drum can be discharged therefrom by opening the valve.

A sight gauge 35 is provided for the tank 17 for indicating the liquid level therein and a pressureg'auge 36 is connected with the upper end of this gauge. A small sight gauge 37 is in communication with the lower part of the tank so that one can tell when the liquid in the tank contains so much foreign matter that the tank must be emptied and recharged. A valve 38 is connected with the bottom of this gauge and by opening this valve, the liquid in the tank can be discharged. A funnel 39 is connected with the tank 17 by a pipe 40 which contains a valve 41 so that by opening the valve 41 and pouring liquid into the funnel, the tank can be refilled with liquid.

A branch pipe 42, containing a valve 43,

` connects the pipe line 15 with the bottom of the tank and by slightly, opening this valve 43, some of the products of combustion will pass through the pipe 42 into the lower part of the tank and thus agitate the liquid therein to prevent sediment from settling to the bottom of the tank. A small pipe 44 connects the discharge of the pump with the lower part of the tank 17 and contains a valve 45 so that when the smoke is heavy or contains a large amount of foreign matter, the valve 45 can be opened so that a portion of the smoke can pass into the bottom of the tank. A sight glass 46 is connected with the lower part of the tank 2O so that by slightly valve 48, the liquid will be discharged from the sight gauge and the tank. The pressure created by the pump will force some of the liquid from the tank 17 into the tank 20 when the apparatus is put in operation.

A pipe 49 connects the lower part of the pipe 9 with a drum 50 and contains a valve 51. The upper end of the drum is connected by a gooseneck pipe 52 with the bottom of a liquid container 53, the major portion of which is preferably formed from glass and carries at its top a screen 54, similar to the screen 30. Liquid is placed in this container 53 through the funnel 55 and the pipe 56 which contains the valve 57. A sight member 58 is connected with the bottom of the member 53so that by opening the valve 59, some of the liquid will pass into the member 58 to permit one to tell whether or not the liquid is so dirty as to need renewal. By opening the valve 60, this liquid can be discharged from the mem'- bers 53 `and 58. This arrangement is used at night or when the fire in the heating apparatus is banked and very little smoke is given off by the fire. Under these conditions, the pump is rendered inactive and the valve 51 opened so that the products of combustion will pass from the pipe 9 through the pipe 49 into the drum 50 and then through the liquid in the member 53, which purifies the same,

through the screen or filter 54. llt will, of

course, be understood that besides purifyin and extracting the heat from the products o combustion, all danger of fires is eliminated as all sparks contained in the products of combustion are extinguished as the products of combustion ass through the device.

HFigure 1 s ows the entire system arranged in a wheeled vehicle 100 so that the s stem can be wheeled from room to room an lace to place to heat the various rooms an places and it will, of course, be understood that the device may be placed in a cabinet of ornamental form so that the parts of the system will not bevisible and that it can be used in any place desired. Awhistle 101 can be connected with the pipe 29, as shown in Figure l.

I use a special kind of chemical mixture in the liquid, such mixture forming the subject matter of another ap lication.

It is though from t e foregoing description that the advantages and novel features ofthe invention will be readily apparent. f

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What I claim is In a device of the kind described, a series of spaced communicatin drums arranged at respectively diii'erent e evations, means effecting communication between the first air of drums of the series at a plurality of dlferent points, a heater having its smoke discharge in communication with the first drum of the series, main and auxiliary tanks containin chemically treated liquid, the auxiliary tan being in communication with the main tank through the top of the latter, and a pump havin its intake inl communication with the ina'l rum of the series and its discharge inA communication with the main tank, the auxild iary tank at its upper end bein in communication with the heater in the re box of the latter, the means effecting communication between the discharge of the pump and the main tank being branched with the branches connected respectively with the top and bottom of the main tank and provided with valves for selectivelyx directing the discharge of the pump into t e top,A or bottom of t e main tank, both the maini-a'nd auxiliary tanks bein provided with filters above the plane of t e liquid contents thereof, and that branch connecting with the top of the main tank discharging below the plane of the level of the liquid contents of the tank. Y

In testimony whereof I aix m si ature.
